Wendy’s massacre survivor JaQuione Johnson has made a miraculous recovery – he can walk, but is still mentally trapped in a nightmare of grief and terror, his family says.

In the May 24 robbery, Johnson, 18, almost died from a bullet to the head that pierced his brain and exited the roof of his mouth. Johnson spat out the slug.

A former Wendy’s employee, John Taylor, and Craig Godineaux have been charged with killing five workers and wounding two during a robbery.

Partially paralyzed, Johnson is still under police guard at an undisclosed hospital because of an anonymous death threat. A menacing telephone caller vowed to “finish them off” – kill Johnson and fellow survivor Patrick Castro, who dragged Johnson to safety.

Although Johnson has improved physically, he spends much of his time in a heartbreaking silent state of anger and denial – in which he refuses to discuss with a psychiatrist or his family his ordeal or the murders.

Johnson has had nightmares so violent that nurses were forced to tie him to his bed to prevent him from pulling out his tubes and wires or hurting himself.

He listens to music in his hospital room and moves to the beat, but his hair has not been trimmed since the shooting because he is terrified to have anyone touch his head.

“If you come near his head to touch him, he’ll put up his hands to protect himself,” said his aunt, Linda Beberaggi of Queens.

“He’s walking now, he’s speaking, but he’s still not speaking about the situation. If you talk about it, he just stares. He’s in deep depression.”

When anyone tries to show him a newspaper clipping about the massacre, “he’ll cover his eyes, he’ll push it away.”

Beberaggi is outraged that her nephew still needs police protection.

“Someone called with a threat and said, ‘I’m gonna finish them off,”’ she said. “They took the other guy into hiding.”

Authorities declined to confirm or deny the threat or discuss security arrangements for the victims.

Beberaggi recalled Johnson telling her recently: “I want to come home.” But the family needs a larger apartment so he can get the physical therapy and psychological counseling he needs, Beberaggi said.

She appealed to the public for donations to the Wendy’s Massacre Survivor Victim’s Fund, JaQuione Johnson, P.O. Box 540894, Flushing, N.Y. 11354.
